Why Dayton will win: Rolling in the deep. The Flyers' rotation includes 11 players averaging double-digit minutes. "There's not much difference between No. 3 and No. 8," coach Archie Miller said. The Flyers rely heavily on Jordan Sibert (12.4 points) and Devin Oliver (11.9 points, 7.5 rebounds). They must come up big and Dayton must drain some threes.

Why Stanford will win: Long and lean. The Cardinal have a substantial height advantage. Dwight Powell (13.9 points, 6.8 boards) runs the show even though he is 6-10. Josh Huestis (11.1 points, 8.2 rebounds, 1.9 blocks) will also be a handful at 6-7.

Did you know? Miller is the first coach in Dayton history to win his first two NCAA tournament games.

Baylor vs. Wisconsin | Time, TV: 7:47 p.m. ET, TBS

Why Wisconsin will win:The Badgers have an efficient offense that tends to carve up opponents (73.9 points and only eight turnovers a game), and they can play with anyone. They have a No. 6 RPI rating and played the nation's second-toughest schedule. They are 6-1 vs. AP top 25 teams and 9-4 against the NCAA tournament field. They have an old-school post game with 7-foot center Frank Kaminsky (13.6 ppg, 6.3 rpg) but can go elsewhere for points, too; guard Ben Brust averages 13.0 and forward Sam Dekker averages 12.7.

Why Baylor will win: The Bears have the kind of size (7-1 center Isaiah Austin and 6-9 forward Cory Jefferson) and athleticism that can bother Wisconsin. Like the Badgers, they are extremely balanced and efficient offensively. Baylor has the nation's seventh-most efficient offense and ranks third nationally in offensive rebounding percentage. Jefferson is the leading scorer at 13.6, followed by guard Brady Heslip (11.9), guard Kenny Chery (11.5) and Austin (11.2). Austin is something of a backstop, and had 18 blocks in the Big 12 tournament.

History lesson:Among coaches in the 700-win club, Wisconsin's Bo Ryan ranks seventh all time in winning percentage (702-222, .759).

Did you know? Baylor has the nation's best postseason winning percentage (17-3, .850) in the last six seasons (8-2 in three NCAAs, 9-1 in two NITs).

SOUTH REGIONAL (MEMPHIS)

Florida (34-2) vs. UCLA (28-8) | Time, TV: 9:45 p.m. ET, CBS

Why UCLA will win: Kyle Anderson. The Bruins' 6-9 point guard is a matchup nightmare. He averages 14.7 points, 8.7 rebounds and 6.5 assists. Who guards him? "We're just going to try to keep him out of the lane, not get a step because he obviously has great length," Florida point guard Scottie Wilbekin said. "If he gets a step, he can finish over and around you." UCLA can de deadly in transition and will try to run, run, run.

Why Florida will win: Defense wins championships. The Gators guard as well as anyone. They can play man. They can go zone. They are not afraid to press. Billy Donovan, with two national championships, has the clear coaching advantage in this one.

History lesson: Florida has knocked UCLA out of the tournament three times in the last eight years (2006, 2007 and 2011). Those are the only meetings between the teams.

Did you know? Donovan is trying to advance to his fourth consecutive Elite Eight.

Why Arizona will win: The Wildcats have a wealth of talent and are tough defensively, having taken on the personality of their coach, Sean Miller, a bulldog of a former point guard from Pitt. The Wildcats slipped in the Pac-12 tournament title game to UCLA but looked like potential national champions in their two victories in their first two NCAA tournament games. They are led by the Pac-12 player of the year, guard Nick Johnson, and league freshman of the year, forward Aaron Gordon. Miller is a proven winner in the NCAA tourney, having taken Arizona to the Sweet 16 three of the last four years and, previously, Xavier to two Sweet 16s.

Why San Diego State will win:They have a scoring machine in 6-3 senior guard Xavier Thames, the Mountain West player of the year, who led the Aztecs in scoring 24 times this year and has 11 20-point games. He is the top remaining scorer in the tournament, averaging 26.5 points in victories against New Mexico State and North Dakota State. He also is a talented defender, as are most of the Aztecs, who are second nationally in scoring defense (56.6) and eighth in field-goal percentage defense (38.3).

History lesson:One of these coaches led a team to an NCAA championship. You remember the saga of Steve Fisher, right? He took over from departing Bill Frieder at the beginning of the 1989 tournament and won his first six games as a head coach, the sixth for the national title.

Did you know?Fisher is one of five coaches left in the tourney who have won a title, along with John Calipari, Billy Donovan, Tom Izzo and Rick Pitino.
